NEVER operate the bender in an explosive atmosphere.
NEVER operate the bender in wet or damp locations.
DO NOT expose the bender to rain.
ALWAYS disconnect the bender from the hydraulic pump before
servicing and when not in use.
ALWAYS inspect the bender before operating. Replace any
damaged, missing or worn parts. Check for alignment of moving
parts, binding of moving parts, breakage of parts and any other
conditions that may effect its operation.
NEVER alter this equipment. Doing so will void the warranty.
ALWAYS keep hands and feet away from pinch points such as
bending shoes, follow bars, saddles, conduit and other moving parts.
ALWAYS use appropriate bending shoe, follow bar and saddle for
the size conduit to be bent.
ALWAYS keep conduit under control when unloading.
ALWAYS keep the path of the bending conduit clear of
obstructions. Make sure all obstacles are clear of the bending
path BEFORE you bend the conduit.
ALWAYS wear approved safety glasses when the bender is
in operation.
ALWAYS wear proper apparel. Do not wear loose clothing, gloves,
neckties, rings, bracelets, or other jewelry which may
get caught in moving parts. Non-slip footwear is recommended.
Wear protective hair covering to contain long hair.
NEVER stand in direct line with the hydraulic cylinder while
operating or servicing the bender. Some parts of the cylinder
are under high pressure and can be propelled with considerable
force.

5. Adjust gauge rod such that gauge reads
zero when the cylinder is fully retracted.
NOTE: To adjust gauge rod, loosen
gauge rod adjusting nuts (see Figure
9A) and adjust rod such that zero (ø) is
flush with the top of the cylinder block
(see Figure 9B).
4. Place the hydraulic cylinder with the cylinder
mounting block between the frame sides as
shown in Figure 9. Insert the two cylinder
block pins into the appropriate frame side
holes for the size of conduit to be bent and
secure each with a spring clip.
NOTE: The hydraulic cylinder with mounting
block in Figure 9 is shown pinned in the
position for bending 4" conduit. The frame
side holes are marked to indicate where to
pin the mounting block for each size.
FIGURE 9
6. Rotate the frame and hydraulic
cylinder so the long side of the
cylinder mounting block is resting
on the floor (See Figure 9C). Then
place the clevis onto the end of the
hydraulic cylinder and secure with the
clevis retaining clip (see Figure 9D).

7. Select the shoe for the size conduit
you will be bending. Place the shoe
between the frame sides as shown,
with the conduit size facing upward.
Align the clevis with the correct hole
on the shoe for the type conduit you
will be bending (Rigid/IMC or EMT).
Insert the clevis pin and secure with
a spring clip (see Figure 10).
NOTE: Arrows on the bending shoe
indicate the correct hole for bending
either Rigid/IMC or EMT conduit (see
Figure 10A).

9. Raise the frame side and place
the correct follow bar for the
size conduit to be bent
between the frame sides as
shown in Figure 10C. The
“START” mark on the follow bar
should be just past the roller
assembly and face upward.
